My problem seams simple and clean, but now the server is apparently set up using netplan to override network interfaces. for me that mean that every description, solution and howto is hart to follow. /etc/network/interfaces states it is out of interest as long as netplan is used, and points to /etc/netplan/. it contains only 50-cloud-init.yaml and it states that it is generated from other (unnamed) sources. where do i go from here. I assume there is a reason for Ubuntu sever to use some packages and not others, and how it is set up and how it is not. i do not want to just start uninstalling and deleting random stuff. I'm running on a Raspberry Pi 3 B+. My "grand plan" is to use my Raspberry Pi as an IoT platform with MQTT++.
